Just thought I'd add--if you have 1600 pixels by 2000 pixels and want it to print 4 x 5, the resolution would be 400 ppi (but the printer would still print 720/1440 or whatever). If you wanted those same pixels to print a 10 x 12.5, then your resolution would only be 160 ppi--and you most likely would see some pixelation. This is where you would want to 'resize' AND 'resample' up to 240 to 300 ppi. Diane
